HERMAN GRANT LARZELERE, 0F NEW YORK, N. Y.

METALLIC MOLD.

To all whom 'it may concern:

Be it known that I, HERMAN GRANT LAR- ZELERE, a citizen of the United States, and a resident of the city of New York, .borough of Manhattan, in the county and State of New York, have invented a new and Improved `Metallic Mold, of which the following isa full, clear, and exact description.

The `object of the invention is to provide a new and improved metallic mold for use in buildinghouses and other structures of concreteor other cementitious and like plastic material, the mold being made in .sections, capable of being readily set up and removably connected with each other, to allow the use of the mold for a great variety of work. The invention consists of novel features `and parts and combinations of the saine, which will be more fully described herein- Aafter and theni pointed out in the claims.

A practical embodiment of the invention :is represented in the` accompanying drawings, forming a part of this specification, in which similar characters of reiferenceindr cate corresponding parts in all the views.

`Pairs of posts A, A are set on the ground and the pairs are spaced suitable distances apart and support by means of clamps B, B the longitudinal rails C, C adapted tocarry sheet metal plates D, D, between which the Specification of Letters Patent. y

Application filed February 11, 1908. Serial No. 415,301.

concrete or other plastic material E is placed, to form a wall or like structure. Each of the rails C, C is preferably in the form of an angle iron, the horizontal member of which rests on an arm B2 of the corresponding clampB o-r B, and the said horizontal member is secured in place by a set screw B3, screwing` in a top member-B4 of the clamp B, as plainly indicated in Figs. 5, 6 and 7. Each clamp B or B can be moved up or down on the post A and then secured in place by its clampingbolt B, so as to hold the clamp in the desired position on the post A or A. The sheet metal plates D, D areeach provided at one side and on the outer face thereof with a joint covering bar F, arranged to overlap the side ot' an ad jacent plate, as plainly indicated in the drawings, and the lower end of the joint covering bar F terminates in a lug F, adapted to engage the vertical member of the rail C `or C, with a view to support the plate D or D under the corresponding rail in conjunction with another lug F 2, secured to the plate D or D at the lower end thereof, and near the free side thereof, as plainly indicated in Fig. 8,

Now by the arrangement described a row of plates D or D can be set, one alongside the other on a rail C or C', the lower Yedges of the plates D or D reaching about midway of the inner face of the vertical member of the rail C or C, so that the several rows of plates D, D form one continuous Surface, between which the concrete or like material E is placed, the horizontal joints between the plates being covered by the rail C or C while the vertical joints are .covered by the covering bars F.

In order-to reinforce the concrete materia-l E, reinforcing strands of twisted wire or other material are employed and arranged transversely (see Figs. 5, G and 7 the ends ofthe strands being passed through apertures C2 formed in the vertical members of the rail C or C', to securely hold the reinforcing members E in position, while the concrete or other plastic material is filled in between the outer and inner sets of plates D and D. W'hen the wall is finished, the strands E can `be readily cut at the aper`- tures C2, to disconnect the strands from the rails C and C.

In order to permit of conveniently hand dling the rails the latter are made in short adjacent ends by plates G, clamped or otherwise fastened to the horizontal members of the rails. As indicated in Fig. 1, the joint of the short rail length is preferably about midway between the adjacent posts A*A or A-A'. Y

In order to give Vthe desired stability to the pairs of posts A, A', the same are preferably connected with each other above the uppermost rail C or C' by links H, each made in sections, having a turn-buckle, to permit of conveniently lengthening or shortening the links, according to the thickness of the wall to be formed by the mold. At a corner of the building corner plates D2 are used (see Figs. 2 and 9) made angular both for the inside and outside corners, each plate being however provided at one side with a joint covering bar F, having a lug F' at its lower end, the other side having a lug F2, to permit of engaging the lugs with the adjacent rails C, C or C', C', at the corner of the mold.

In order to connect the inner rails C', C', at the corner of the mold (see Figs. 3 and Ll), use is made of a connecting bar I', having` at one end an upturned clamping member I' provided with a set screw I2, for securing this end of the bar I to the hori- Zontal member of one rail C', the other end of the bar I being secured by, upturned members I3 and set screws I4 to the horizontal member of the adjacent corner rail C.

In order to form a bay E2 in the wall the following arrangement is made, special reference being had to Fig. 2: The adjacent rails C' terminate a short distance from the intended bay, and to the ends of these two rails C' is secured an auxiliary rail C", by suitable clamps J, and this auxiliary rail C4 supports angular corner pieces K, K' (see Figs. l0 and 1l) by the use of the lugs F2, F3, the same as on the main plates D, D', the lugs F2 being formed on the lower ends of the joint covering bars F. Between the corner plates K, K' I place one, two or more main plates D according to the length of the bay, as'will be readily understood by reference to Fig. 2.

From the foregoing it will be seen that by the arrangement described the mold can be readily built up to form walls of anydesired thickness, length and height in a very convenient and simple manner, it being understood that if the lower portion of the wall has set and hardened then the corre` sponding clamps B, B', rails C, C' and plates D, D' can be removed and used as a continuation of the upper portion of the mold, so that it requires comparatively a small number of individual parts to forni a wall of any desired height and length. By making the parts of metal they readily maintain their shape and consequently can be used over and over again without danger permit their ready removall after the wall has been built up to within a short distance 1 of the upper end of a core. The detail construction of the core N is as follows: rIhe body of the core N is formed of two main members N', N2, curved at the ends toward each other and provided with overlapping tops N3, N4. Between thev ends of the main members N', N2 extend retractable bars 'O connected by links 0 with the ends of arms O2, secured at their middle on a vertical shaft O3, journaled in suitable bearings P, carried loosely in notches formed in channel irons N5, N6, riveted to the inside of the main members N', N2. The upper end ofthe shaft O3 extends through openings in the tops N2, N4, and the'upper outer terminal of the shaft O3 is made polygonal, to permit the convenient application of a crank wrench or lother tool, to turn the shaft O2 and to cause the arm O2 vand links O' to move the bars O, O inward and out of position between the ends of the main members N', N2, with a view to permit the latter to move toward ench other. The core is thus collapsed and can'be readily drawn out of the concrete E, use being preferably made for this purpose of a suitable hoisting device connected with rings Q, attached to the top N4. The links O are guided in suitable guideways O2 attached to the inside of the main members N', N2, as plainly shown in Figs. 13 and l5. v

` In using the mold, the pairs of posts A, A' are set up on the ground, and, if desired, anchored by suitable devices R, as indicated at the left in Fig. l. Clamps B, B' are then attached to the posts at the lower ends thereof, to rest on the ground and then the lowermost rails C,A C are secured to the clamps B, B'. Another set of rails C, C higher up is then secured by clamps B, B' Ato the posts, after which the main plates D, D' are placed in position to form a space, into which the cores are set and which space is then filled with the plastic material. After the plastic material has been filled in and properly tamped to about the lengths of the first row of main plates D, D',then a second row of plates D, D' is set up, and the above-described operation is repeated. In the meantime the plastic material in the lower courses may have set sufficiently to allow removal of the lower rows of plates D, D', their supporting rails C, C' and clamps B, B for re-use above, as before explained. I/Vhen the wall material has reached about the height of a lOO llO

coreN, the latter is first collapsed and then raised clear-'of the wall, after which it is `expanded by turning the shaft O3 in the reverse direction and to again pass the joint bars O between the ends of the main members'N, N2. i The core is then again in position for re-use.

j Having thus described my invention, I claim as new and desire to secure by Letters Patent:
